LUG-STRAP' SUPPORT.

Specification of Letters Patent.

Patented May 4, 1920.

Application flied December 22, 1919i serial' No; 346,474.

To all 1li/0m t may concern:

Be it known that I, .Ii-mins F. SMITH, a citizen of the United States', residing at Gaffney, in the county of Cherokee and State of South Carolina', have invented new and useful Improvements in Lug-Strap Supports, of which the following is a specificationl This invention comprehends'y the provision of an attachment for the picker arm'of a loom, the attachment being designed. to reinforce the arm with a view of preventing breakage of the latter, or undue wear of the same, and also designed to maintain the lug strap operatively positioned'v upon the arm.

`rThe nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawingthe invention residing' in the construction, combinat'ion and arrangement of parts as claimed.

In the drawing forming part of thi'sspecificat'ion like numerals of referei'ice indicate similar parts in the severa-l views and wherein f- Figure 1 is a side elevation of a portion of a picker arm showing the attachment associated therewith.

Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. 1.

Fig. 3 is a perspective view of the attachment. i

Referring to the drawing in detail, 10 indicates the picker arm of a loom, 11 the strap for the lug, while the attachment is indicated generally at A and clearly illustrated in Fig. 3.

The attachment is inthe form of -a clamp adapted to embrace the picker arm 10 and is constructed of metal for the purpose of reinforcing the arm with a view of preventing breakage thereof or undue wear of the same, by constant impact between the arm and the lug strap. The clamp is shaped to provide spaced upper and lower U-shaped portions 12 and 13 respectively, both of which portions project in a common direction from the body portion 14 of the clamp which connects these portions together. The U-shaped portion 12 is of a greater depth than the U- shaped portion 13, as this portion of the clamp is designed to support the lug strap 11 in a manner whereby the strap is prohibited from coming in Contact with the picker arm 10. Both the U-shaped portions 12` and lrespectively embrace the arm 10 in a manner whereby the body portion 1.4L of the clamp lies against the rear edge of the arm', the Uf-shapedportions projecting beyond the forward edge of the arm and' having their extremities connected by means of bolts and nuts, or other suitable fastening. means indicated at 15. The body portion 14`of the' clamp is provided with an aperture 16, which receives a pin or the likeI 17 projecting from the rear edge of the arm 10 to prevent the clamp in its entirety from slipping downwardly upon the arm 10 when it is in its applied position.

The opposed sides of the U-shaped portion 12 are bent from their lower edges to' provide hook-like supports 17 for the lug strap`11', the parallel limb of this strap being arranged for sliding movement within' the hook-like members; Each hook comprises a base 18 and a vertically disposed member 19, spaced from the adjacent side of the U-s'haped portion 12, of 'which it forms a part. The opposite ends of the base 18 of eachhook-like member are curved downwardly, while the vertically disposed portion 19 of each hook like member has its opposite ends curved outwardly so that the ends of the base and vertically disposed portion are prevented from scraping against the lug strap during the operation of the latter. Formed on the upper end of the clamp is a transversely disposed member 20 which projects beyond the opposite sides of the arm 10 and disposed at an angle with respect to the rear edge of the arm as shown. This transverse member 2() `coperates with the hook-like members 17 to prevent the lug strap from jumping or moving out of the attachment as will be readily understood. WVhile the U-shaped portion 12 prevents the parallel limbs of the lug strap from coming in Contact withthe picker arm 10, so also does the body portion 14 prevent the end of the strap 11 from coming in contact with the rear edge of the arm. Consequently the arm is materially strengthened, and `protected from undue wear incident to the impact between the said arm and said lug strap.

While I have shown and described what I consider the preferred. embodiment of the invention, I desire to have it understood that I do not limit myself in this connection, and that such changes may be resorted to when desired as fall Within the scope of what is claimed.

Having thus described my invention What I claim as new is l. The combination With a picker arm and lug strap, of an attachment for said arm comprising a member designed to brace the arm, means lformed on the sides of said member for supporting the lug strap, and an extension formed on the front of said member and cooperating with the said means for preventing the lug strap from being casually separatediirom said member.

2. The combination with a picker arm and lug strap, ot' an attachment for said arm comprising a member designed to embrace said arm, opposed hooks carried by the sides of said member for supporting thel lug strap and an extension projecting from the front of said member above said strap and cooperating with said hooks to prevent the strap 'from being casually separated from the member as specified.

3. The combination with a picker arm and lug strap, of an attachment for said arm comprising a member designed to embrace the arm. opposed hooks formed on the sides of said member for supporting the lug strap, an extension' projecting from said member and arranged above the strap, the front of said extension cope ating with the hooks to revent the stra a from beine` cas ually separated from the member, and a bottom and vertical portion of cach hook having their ends curved away from said strap for the purpose specified.

4,. The combination with a picker arm and lug strap, of an attachment for said arm comprising spaced U-shaped members embracing said arm, a strip connecting the U-shaped members, and arranged to engage one edge oi' said arm, and means for securing the U-shaped members in position above the arm, opposed hooks carried by one of said U-shaped members, and constituting a support for said lug strap, and an extension projecting from said Ushaped member above said strap, said extension coperating With the hooks to hold the strap operatively positioned upon the arm.

5. The combination with a picker arm and lug strap, of an attachment for said arm comprising spaced U-shaped members, embracing said arm, a strip connecting' the U- shaped ,members and arranged to engage against one edge of the arm, said strip having an opening, a lug projecting from said arm through the opening to prevent the attachment from moving longitudinally of the arm, means for holding the U- shaped portion about said arm, opposed lugs carried by one of said U-shaped portions and constituting a support 'for said. lug strap, and an extension projecting from said U-shaped portion and disposed With respect to said hook and strap to cooperate with the hooks to prevent the strap from becoming casually separated from said attachment.

In testimony whereof I ailix my signature.

JAMES F. SMITH.
